Method Summary

void	close() this method is called by the PDP framework to indicate that the interceptor now should remove all state that was allocated in the initialize call
org.w3c.dom.Node	getPolicy(org.w3c.dom.Node policy) gets the current policy of the PDP
java.lang.String[]	getPolicyNames() gets the names (typically uris) of all the policies that the PDP supports
void	initialize(PDPConfig config, java.lang.String name, java.lang.String _servicePath) Initializes the interceptor with configuration information that are valid up until the point when close is called.
boolean	isPermitted(javax.security.auth.Subject peerSubject, javax.xml.rpc.handler.MessageContext context, javax.xml.namespace.QName op) this operation is called by the PDP Framework whenever the application needs to call secured operations.
org.w3c.dom.Node	setPolicy(org.w3c.dom.Node policy) sets the current policy of the PDP

                throws InitializeException

Description copied from interface: Interceptor

Initializes the interceptor with configuration information that are valid up until the point when close is called.

Specified by:

initialize in interface Interceptor

Parameters:

config - holding interceptor specific configuration values, that may be obtained using the name paramter

name - the name that should be used to access all the interceptor local configuration

_servicePath - the id in common for all interceptors in a chain (it is valid up until close is called) if close is not called the interceptor may assume that the id still exists after a process restart

Throws:

InitializeException

getPolicyNames

public java.lang.String[] getPolicyNames()

Description copied from interface: PDP

gets the names (typically uris) of all the policies that the PDP supports

Specified by:

getPolicyNames in interface PDP

Returns:

array of policy names

public org.w3c.dom.Node getPolicy(org.w3c.dom.Node policy)
                           throws InvalidPolicyException

Description copied from interface: PDP

gets the current policy of the PDP

Specified by:

getPolicy in interface PDP

Parameters:

policy - may be used to query for a subset of a policy

Returns:

the policy

Throws:

InvalidPolicyException

setPolicy

public org.w3c.dom.Node setPolicy(org.w3c.dom.Node policy)
                           throws InvalidPolicyException

Description copied from interface: PDP

sets the current policy of the PDP

Specified by:

setPolicy in interface PDP

Parameters:

policy - new policy

Returns:

optional set policy result

Throws:

InvalidPolicyException

close

public void close()
           throws CloseException

Description copied from interface: Interceptor

this method is called by the PDP framework to indicate that the interceptor now should remove all state that was allocated in the initialize call

Specified by:

Throws:

CloseException

isPermitted

public boolean isPermitted(javax.security.auth.Subject peerSubject,
                           javax.xml.rpc.handler.MessageContext context,
                           javax.xml.namespace.QName op)
                    throws AuthorizationException

Description copied from interface: PDP

this operation is called by the PDP Framework whenever the application needs to call secured operations. The PDP should return true if the local policy allows the subject to invoke the operation. If the PDP has no local knowledge about whether the operation is allowed or not it should return false to allow other PDPs and PIPs in the chain to continue the evaluation. Obligations to be read by other PIPs or PDPs may be set as attributes in the Subject credentials.

Specified by:

isPermitted in interface PDP

Parameters:

peerSubject - authenticated client subject with credentials and attributes

context - holds properties of this XML message exchange

op - operation that the subject wants to invoke

Throws:

AuthorizationException
